Skills & Interests: 

Research Interests
Cryogenic and geodynamic systems on continental margins:
 •  Gas hydrates in relation to submarine fluid flow and seabed seepage (mud volcanoes, pockmarks)
 •  Glaciation of continental margins and sedimentary basins (meltwater drainage beneath ice sheets)
 •  Post-rift epeirogenic movements as dynamic topographic responses to upper mantle convection

Key Achievements
 •  Discovery of a gas hydrate system on the Nile deep-sea fan (HYDRANIL project, 2009-present)
 •  Co-discovery of mud volcanoes on the Calabrian Arc (EC HERMES-HYDRAMED, 2004-2009)
 •  Model of dynamic topographic uplift of 'passive' continental margins (EC STRATAGEM, 2003-2005)
 •  Pioneering application of 3D seismic data to Quaternary glacigenic successions (PhD, 1990-1996)

Methodologies
Acquisition and  analysis of multi-disciplinary marine geophysical & geological datasets, including:
 •  Water column and seabed imagery - multibeam echosounders and sidescan sonar systems
 •  Seismic reflection data - high resolution single-channel and 2D & 3D multi-channel data
 •  Cores & well data: ltiho-stratigraphy from sediment cores, well cuttings and geophysical logs
 •  ROVs & AUVs - Remotely Operated Vehicles and Autonomous Underwater Vehicles
 •  Geothermal measurements - using thermal probes from surface vessels and ROVs

Field Experience (Oceanographic Campaigns)
Participant in 14 campaigns to the Mediterranean Sea, the North and South Atlantic Oceans and the Canadian Arctic (>10 months at sea); Chief Scientist on 3 campaigns.

Major projects: 

GLACIATION OF LOW-LATITUDE CONTINENTAL MARGINS - THE CELTIC SEA
Investigations of submerged glacial landscapes at the SW margin of the last Eurasian ice sheet, where questions surround both the maximum extent of glaciation and the dynamics of a major (Irish Sea) ice stream. Research theme resulting from an International Polar Year (IPY) proposal (Praeg 2005, IPY Expression of Interest 529, see http://classic.ipy.org/), supported by the following intiatives:

•  IPY GLAMAR: GLAcial Meltwater and Continental MARgins (2012-2014)
OGS-led IPY collaboration with partners in Ireland (NUIM), UK (BGS) and Canada (GSC) to analyse data acquired during the 2009 GLAMAR campaign and support OGS participation in follow-on Irish campaigns. Funded by Italian PNRA (€40,000)

•  GATEWAYS I: Ice Streams and Iceberg Calving Gateways SW of Ireland (2012)
Irish-led research campaign to acquire geophysical and geological data from the glaciated continental shelf offshore SW Ireland. Supported by Irish National Ship-Time Progamme (http://www.marine.ie) (r/v Celtic Voyager, 21 April-12 May 2012, 21 days ship-time, equivalent value €160,000); OGS participation (including Chief Scientist Leg 1) supported by IPY GLAMAR.

•  RIDGES : Regionally IntegrateD GEological Mapping of the Celtic Sea (2009-2010)
Irish-led collaboration to undertake post-campaign analyses of the 2009 GLAMAR dataset, collaboration between researchers in Ireland (NUIM), Italy (OGS) and the UK (BGS). INFOMAR project INF-09-14-MCC (12 months, €29,409).

•  GLAMAR: GLAcial Meltwater & the Sedimentary Architecture of Continental Margins (2009)
OGS research campaign, in collaboration with Irish (NUIM, INFOMAR) and UK partners. Undertaken as an OGS contribution to the International Polar Year (r/v OGS Explora, 04-31 August 2009, 28 days ship-time, equivalent value c. €420,000 equivalent value).
 

GAS HYDRATES AND SEABED SEEPAGE IN THE MEDITERRANEAN SEA
Ongoing research into submarine fluid flow systems, which has led to discoveries of mud volcanoes and gas hydrates in the Mediterranean Sea in collaboration with European and Brazilian partners. Research theme supported by the following initiatives:

•  HYDRANIL: Assessing the Gas Hydrate System on the Nile Deep-Sea Fan (2009-present)
OGS-led collaboration with partners in France (Géoazur), Germany (Jacobs University Bremen) and Brazil (PUCRS/CEPAC)  to investigate fluid systems on the Nile Fan (seismic data sharing from 2008 leading to discovery of gas hydrate BSR; acquisition of data from active pockmarks during French APINIL campaign in 2011). OGS-supported international collaboration.

•  APINIL: intéraction climAt-Processus-fluIde sur le NIL (2011)
French-led research campaign to investigate sedimentary processes on the Nile fan (r/v Le Suroît, 16/09-24/10 2011, 40 days ship-time); OGS participation in Leg 1 (AUV) and 2 (PASISAR deep-towed sidescan and seismic), OGS-led investigations of active pockmarks in collaboration with Brazilian and French partners in HYDRANIL during Leg 3 (coring)

•  HERMES: Hotspot Ecosystem Research on the Margins of European Seas (2005-2009)
EC FP6 Integrated Project with 50 partners (OGS PI S. Ceramicola, budget c. €400,000); supporting OGS-led discovery and investigation of mud volcanoes on the Calabrian accretionary prism, and investigations of gas hydrates on the Nile fan, in collaboration with the EC HYRAMED project
